Appengine error running GWT expense sample

[ocramitnaf]

Removing gae folders from shared and server worked for me as well, but refreshing ~m2 didn't do anything.

I'm having the same problem on a project created from my own custom roo script

hi dankib01

Just apply the same fix that works with expenses.roo

which is to remove all gae folders
1. client/scaffold
2. Server
3. Shared

...folders....in both src and target directories

this works for any custom scripts that I've written

Hi Simon - I saw that too, but it begs the questions.
1. Why is Roo creating unnecessary classes? (are they really unnecessary?)
2. Why isn't Roo including the necessary references?
3. Did anyone test this?

Cheers

It would be great to have more details on how the problem is occurring so we can fix it.

Is this happening with new projects (i.e. empty directory projects)?

Yes. My script creates a new project in a empty folder.

Here's a chopped version

// Spring Roo UNKNOWN VERSION log opened at 2010-11-20 15:29:04
project --topLevelPackage com.getrolling.cis --projectName CisRoo 

persistence setup --provider HIBERNATE --database HYPERSONIC_PERSISTENT 

entity --class ~server.domain.Photo  --testAutomatically
field string --fieldName descr --notNull 
field string --fieldName fileName --notNull 
field number --fieldName height --type java.lang.Integer --min 1
field number --fieldName width --type java.lang.Integer --min 1

enum type --class ~shared.Ability
enum constant --name BEGINNER
enum constant --name INTERMEDIATE
enum constant --name ADVANCED

//... create some more entities & enums

perform tests

gwt setup

logging setup --level INFO
//end

As everyone else does, I end up with some classes that import

import com.google.appengine.api.users.User;
import com.google.appengine.api.users.UserService;
import com.google.appengine.api.users.UserServiceFactory;

and those imports can't be resolved, so the build fails.

Hi All

I just download the latest 1.1.1 and I'm trying to run the sample apps..

I'm using roo1.1.1 and GWT 2.1.1

but get this error.....does anyone know why?

I've followed this instruction in the pdf doc's for 1.1.1
"The GWT maven artifacts in your local maven repository should be removed so they can
be replaced with the latest versions. Make sure to delete ~/.m2/repository/com/google/gwt and
org/codehaus/mojo/gwt-maven-plugin."

But I was getting the same error even before I made these changes

any help is appreciated

simon

......

try this in spring roo
dependency add --groupId com.google.appengine --artifactId appengine-api-1.0-sdk --version 1.4.0

but when i run mvn gwt:run
